power steering pump question

OK, power steering was working great. Next day power steering pump started leaking around the high pressure hose where it goes into the reservoir. In the process of changing the line, where the hose goes in the reservoir I was having trouble starting the threads so i stuck my finger in the pump to see if there was somthing stoping it. I could feel something in there that felt like it had the resistance of a spring behind it. When I took my finger out it fell out and it was a small cylinder. I ended up taking the pump off so i could look into the hole and nothing there. I put the cylinder back in, put the new hose on and tried bleeding the bleeding the system. No luck. The fluid doesnt seem to be circulating at all.

Did I do something wrong when the small cylinder fell out. I hope the Ford master mechanics on this site can help. I know enough to fix things but not rebuild parts. Please help!

You'll have better luck if you tell us a bit more about the pump. You have indicated in your Forum ID that you have a 1966 F-100. Is this the truck this pump is in? Can you tell us what type it is? Is it a Thompson? That's the round one with the lines connecting to the back -- one threaded and one not threaded.

1965/77: If the P/S pressure hose threads onto the pump, it has a steel reservoir.

1978: FoMoCo changed the P/S pump on everything (except Econolines & Passenger Cars w/Hydro-Boost)), has a plastic reservoir.

The P/S pressure hose has a straight tube with an o-ring on it at the pump end. Connects to the pump with a qwik connect fitting.

Thanks for the reply. It is a 66 body but it sets on a 78 chassis. It is a 460.

The reservoir is plastic and the hose fitting screws in to a fitting that is in the side of the pump just below the fill tube on the reservoir.

This link shows a picture of the exact way my system looks and if you look at the top picture and see where the fill tube is you will see the fitting that is in the pump which the pressure line screws into. This is where I could feel a cylinder of some kind that felt like it had a spring against it when I pushed it. Then after I took the pump clear off and put it back in, it slide in with not pressure behind it

Impossible: Plastic Reservoir: EVERY P/S pressure hose connects to the pump with a QWIK CONNECT FITTING

Look in the 1973/79 Ford truck & car parts catalogs, see if you can find a P/S Pressure hose that threads onto a plastic reservoir pump.

Lotsa luck, cuz there's no such thing! I sold these parts when these vehicles were brand new, then thru 1997, so I know what the hell I'm talking about.

= Autozone pic same as Ford parts catalog pic...fitting that's shown is a qwik connect! You have the wrong P/S hose if it has threads on the pump end.

Thanks for the input. Look at the link I attached and you will see the exact sysytem I have. My mistake when I said the the pressure hose threads into the reservoir, it threads into the pump where the reservoir wraps around it. It doesn't show in the picture but there is circle cut out of the plastic reservoir where the metal fitting is. I know the reservoir moves slightly because I was having trouble getting the fitting started and it was because the reservoir was shifted slightly and was covering up just a very small part of the fitting hole on the pump and wouldnt let me start the fitting. That was another reason I took the pump completley off because I couldn't get the fitting to start.

Again: Plastic Reservoir pump: P/S Pressure Hose has a straight tube with an o-ring on it on the pump end, connects to the pump with a qwik connect fitting.

1978/79 F100/350, Bronco & Passenger Cars (w/o Hydro-Boost) = Ford part numbers:

388748-S .. O-Ring-Use with 5/16" qwik connect fitting.

388749-S .. O-Ring-Use with 3/8" qwik connect fitting.

In case you missed it, see last line in post 5.

I don't want to tell you you're wrong, but the picture shown does not show a quick connect on either end. Look at the second picture down and you ca see the hose where it goes in to the pump right below the reservoir fill tube.

Here is the hose I bought, that matches the hose i took off, which came straight from napa's parts book.

NAPA parts catalog isn't a FoMoCo parts catalog.
Since the autozone pic matches the Ford parts catalog pic, the fitting that is shown is a qwik connect.

What someone may have done, is removed the qwik connect, used another fitting to get the their threaded hose to fit. The thing is, on the qwik connect fitting are two more o-rings.

So, now the hose is leaking and there's nothing you can do about because the fitting is wrong as is the hose.

FTE member mikeo0o0o0 has the 1973/79 Ford Light Truck Parts Catalog on a CD, scans/posts pics for members. Ask him to post this: Illustration Section 36, Pages 25 & 26.

Page 25 shows an exploded view of the plastic reservoir pump. Page 26 shows the pump, brackets, hose routings for 1978/79 F100/350 2WD's.

Once you see these pics, you'll know who is right and who is wong. Sorry, I couldn't resist.

Check out the link below. It shows a Bronco pump that appears to be the same as yours. The second photo shows a cylinder and spring removed from inside the fitting that is threaded into the body. Does this look like the cylinder that came out of yours? If so, this photo may help as it shows the orientation of the cylinder and the spring inside the fitting.

Old Coyote you rock!!! That is exactly it. The spring must have came out with out me knowing. Your awesome! I will still have to take everything back off probly to get the cylinder out to put the spring behind but that is it?

NumberDummy, the hose isn't leaking now, that is what started this. the new hose I put on fixed it, and i'm sorry, but the fitting is exactly like the picture old coyote directed me to and it is not a qwick connect and it is exactly as shown i the napa book, pump and hose. I gave napa my year, model, engine size and they pulled this hose up with fitting as shown which is not a quick connect fitting

not sure where we are missing each other on this number dummy, but thanks for the help. Especially old coyote!

I'm glad it helped you at least identify the problem. Good luck finding that spring and getting it back together.

I don't know how to explain it any clearer. It is NOT a quick connect fitting. Not on mine, not in Coyotes second pick, not in napa's book, not in geek parts book, not in autozone book. I'm going to take a picture of mine tonight and post so you can see. And I know you are going to say "we'll someone changed something, becauses that isn't stock, because it is. And again I know its stock because it is the pump as well as the fitting on the pump that everyone I have talked to shows.

It's not stock, I compared the exploded view of the parts catalog pic to the parts in that second pic, gave the actual FoMoCo descriptions of the parts.

Once you look at the Ford parts catalog pic, you will see that. There is no, repeat no such thing as a P/S pressure hose that threads onto a plastic reservoir pump.

I'm thru with this thread, lotsa luck fixing your leaking hose.
